Fignre=1-.-is--a cross-section through the cage showing one of the rolls in dotted lines; Fig. 2 is a section on line :vw Fig. 1; Fig. 3 is a perspective. view-of thefsheet metal stamping -forming'fthe reinforcement; Fig. 4 is a section showing the manner of spinning over the sheet metal flange of the cage 40. to form the retainer for the rolls; Fig. 5 is a section similar to Fig. 4 showing a modi fied construction; and Fig. 6 illustrates a detail of construction.

My improved cage is applicable to that 5 type of roller bearings which are designed 4 for taking care of both radial and end thrust, and in which the end thrust is trans mitted to enlarged heads upon the rolls. It is desimble'to hold the rolls in proper spaced 5() relation, and for this purpose .the construction is provided with spacer hearings, while the rolls are held from endwise displacement by a bent flange engaging the enlarged heads. With the construction shown in Figs. 1

and 2, the spacer portion of the cage is formed of an integral die casting having aseries of spacer bearings with concave faces for receivingthe' respective rolls. To strengthen this die casting it is reinforced by an embedded core, preferably a sheet steel stamping, and the retainingflange for the rolls is preferably formed integral with this core, i

- In detail, A is the reinforcement or core,

which is preferably formed of a sheet metal stamping. As shown, this is of conical form and is provided withuan inwardly-turned: annular flange B at its smaller end, and an. outwardly-turned annular. flange C-at its large end. Intermediate lheseflang'es the conical portion is cut away at D to form a series of spokes E whichare of lesser width than the space between adjacent rolls of the l earing, dricalportion F, which,- after the rolls. are

in place is spun downto form a. retainer.

' The core or reinforcement A formed as described is placed in the die in which the, cast is formed, .so that the spokes E extend, centrally between the cores that form't-he I roll recesses. The metal is then castinthe die and surrounds the spokes E ,'as shown. at G in Fig. 2, forming segmental bearings. for engaging the rolls; The cast metal also extends downward below the flange B to completely enibed the same,l)ut at the upper end the cast metal preferably terminates in the plane of the flange C. ,Thus a ser es of open conical pockets arerfornied between the bearings G for the reception of the conical rolls, while the'enlargedheads of said rolls, indicated at H, and which take the end thrust. overlap said flange C. In assmnbling the bearing, the rolls are first placed in the pockets o,r recesses between the bcarings G,,zifter which the cylin drical flange F is spur. over as indicated at I v in Fig. 4, thereby forming a retainer which prevents the endwisedisengagement of the rolls. The strcrglrh imparted to the struc ture by the sheet metal reinforcement is sufficient to withstand any ordinary stresssuch as produced by the accidental dropping of the cage, without either breakage or deformation. Thus a thoroughly practical con strnction is obtained and one which possesses peculiar advantages. .l n the modified construction shown in Fig. 5, in place of forming the spacer portions Beyond the, flange C is a cyline 75 i 1.
